Description

In Flink 1.9, we already introduced a basic SQL DDL to create a table. However, it doesn’t support to define time attributes in SQL DDL yet. Time attribute is a basic information required by time-based operations such as windows in both Table API and SQL. That means, currently, users can’t apply window operations on the tables created by DDL. Meanwhile, we received a lot of requirements from the community to define event time in DDL since 1.9 released. It will be a great benefit to support define time attribute in SQL.

This is the umbrella issue to track all the sub-tasks.
